Abstract Poly( d,l -lactide) was synthesized with the ZnO,SnCl\-2 or Stannous Octoate as catalyst,respectively. The molecular weight was measured by chemical titration and viscosity. The resultant poly( d,l -lactide) was characterized by FTIR and DSC. The result shows the polymer is amorphous,and Tg is 53.3��.
